The son of a senior Irish prison officer murdered by the IRA has confronted Gerry Adams and accused him of lying in the Dail.

Austin Stack said Mr Adams should give police the name of a senior republican who met the Sinn Fein leader, Mr Stack and his brother Oliver.

Mr Stack told Mr Adams it would be an absolute disgrace if he didn't do so.

Brian Stack was shot in the back of the neck as he left a boxing match in 1983.

Mr Stack, who was the chief prison officer at the high-security Portlaoise Prison, was left paralysed and died 18 months later.

In a statement to the Dail (parliament) on Wednesday, Mr Adams said that during Ireland's general election campaign in February, he had emailed Irish police commissioner Noírín O'Sullivan a list of four republicans who may have been involved.

The Sinn Féin leader said he had been given the names by Austin Stack, who is a senior prison officer himself.

Mr Adams said Austin Stack told him the names were given to him (Mr Stack) by journalists and police sources.
